Dark Noir Spider Man 4K Live Wallpaper

AI Security Review

Evidence context: threat category none; evidence quality moderate.

This extension, "Dark Noir Spider Man 4K Live Wallpaper," claims to provide a live wallpaper for Chrome's new tab page. The evidence bundle contains 779 total findings, but the distribution reveals a classic false positive pattern: 762 IoC findings with zero malware signatures, zero obfuscation detections, and zero network behavior findings.

The IoC findings list domains like d.cd, wsj.mr, w.aw, 3.ua, 7.ge, s.mc, b.gy, g.lr, and oczm.be extracted from files. While these domains appear unusual, they are only detected as extracted IoCs with no corresponding network findings. The absence of network findings ("network":"0" in findings_summary) means these domains are not actively being contacted by the extension during runtime. This pattern is consistent with the XIOC extractor flagging embedded strings, bundled dependencies, or asset references rather than actual malicious communication.

Critically, there are zero malware signatures ("malware-signature":"0") and zero obfuscation findings ("obfuscation":"0"). Malicious extensions that use suspicious domains typically employ obfuscation to hide their behavior and trigger malware signatures. The 17 code-smell findings ("code-smell":17) are classified as low severity and represent known noise sources per the CVEQ false positive documentation.

The developer is listed as "[email protected]," an email address rather than a verified organization, and the extension has only 64 users. While this anonymity is a mild concern, it does not constitute evidence of malicious intent without corroborating behavioral findings.

Counterargument: A skeptic would point to the 762 IoC findings and the suspicious nature of short domains with unusual TLDs as evidence of potential browser hijacking or data exfiltration. However, this argument fails because IoC count alone is meaningless per the CVEQ guidelines. Without malware signatures, obfuscation, or actual network behavior findings, these IoCs cannot be confirmed as malicious. The extension's stated purpose (live wallpaper) is legitimate, and the findings pattern matches known false positive drivers rather than confirmed threat indicators.

Key Reasons

• Zero malware signatures despite 762 IoC findings
• Zero obfuscation detections
• Zero network behavior findings
• IoCs are extracted strings with no runtime evidence
• Extension purpose (live wallpaper) is legitimate

False Positive Considerations

• XIOC extractor false positives on embedded strings
• Bundled dependencies triggering domain extractions
• Code-smell findings classified as low severity noise
